Specification forming part of Letters Patent No. 39,826, dated September 8, 1863.

To all whom it may concern.'

Be it known that we, RICHARD MOHLER and JOHN BECKER, both of Lancaster county, in the State of Pennsylvania, have jointly invented a new and improved mode and arrangement of knockers or beaters operating eX- ternally against the reels or hour-bolts used in griet-mills and we do hereby declare that the followingis a full and exact description thereof, :reference being had to the accompanying drawings, making a part of this specification, with the letters of reference marked thereon.

Figure l is a perspective view of the bolting-chest A, open lid L, showing the lower portion of the bolting-reel and cloth B, eX- ternal ribs C,rail D, on its end support, E, with a series of poised levers or beaters, F, in place. Fig. 2 shows the arrangement of the beaters detached; Fig. 3, a single beater raised out of its slot d in the rail D, (shown inpart,) with the upper long groove, g, in which the pin G or pivot of the beater F is lodged, and on which it has its vibrating motion.`

y This pivot can be set thronghany one of a double series of holes, h, shown.

The construction is as simple as its operation and readily understood by the drawings. The bolt is of the ordinary kind in use, and the only addition thereto is a partial rib over each beater, or a single rib along the entire length of the bolt, applied over cach angle on the outer surface. These ribs o are raised from the cloth and inner'rib of the reel by means of filling or washers of any desired thickness around each screw, nail, or bolt employed. This prevents cutting the cloth and aids the vibrating action of the beaters. The end supports, E E', for the rail D, and its beaters or levers F may also be made adjust able for elevating or lowering the rail by slots and screws through the ends of the boltingchest, or affixed permanently at the proper height. The rail D can be drawn in or out beneath the bolt, sliding on the end pieces, adjustable to any position most desirable with the vibrating beaters or lever-knockers F, so poised that the revolutions of the bolt will bring each of its external ribs, c, in contact with the entire series as to depress the inner ends, f,of the levers F. The outer ends being weightier will necessarily drop the moment the reel or rib of the bolt passes over and releases the same, causing the levers to strike upward against the succeeding ribs in quick succession as the bolt revolves over l them. The force of the beaters or levers is easily regulated by changing the fulcruln or range of adjustment to a single beater or tov the entire series with the greatest ease to produce any desired amount of force in the upward stroke-this together with the fact that a blow or concussion on the outside of the reel or bolt and at its lower point is more efficacious in producing the result to be accomplished by knockers than when the concussion is in any manner produced within the bolt, to say nothing of the difficulty of getting at them in order to regulate the same, which requires the interruption of the bolting at best when effected by any arrangement employed now in use. This position and arrangement of the beaters is deemed a decided improvement, and greatly facilitates the process of bolting. A little reiiection upon the law governing con- `cussions cannot fail to convince the mind,

what actual experiment has clearly proved, that a blow struck on the outside, beneath the bolt, where the meal is lodged anddischarged, is the proper and most effectual point for producing the desired result. Flour, like dust, reacts in the direction from whence the blow comes, especially if the opposite side af. fords any elastic resistance-such, for instance, as your thigh under the cloth of your pantaloons--a blow with your hand will bring the dust concealed in the meshes of the cloth to the surface. This fact is readily demonstrated, hence no further argument is required. Besides, a blow on the top of the bolt,` where it is empty, although it clears the meshes by discharging the our both without and within the bolt, scattering it in every direction within the bolt and boltingchest, much of which again settles both on the outer-and inner surface of the bolting-cloth, and more or less again clogs the saine in its revolution before the previously-cleared surface comes to the discharging-point, thus losing the efficacy of the concussion to a great degree, whereas a lectively by means' of the holes h, pins G, rail blow beneath simultaneously With the drop- D, and end supports, E, operating substanping of the Hour greatly augments its distially in the manner specified against the untharge. This arrangement is also as cheap der surface of the reel, as shown.

and simple of application as it is efficient in its operation. R' What We claim as our invention, and desire p to secure by Letters Patent, is- Witnesses:

The arrangement of a series of levers or GEO. SANDERsoN, beaters, F, made adjustable separately or col- JACOB STAUFFER.
